CATO supplies Triisopropyl((4-((4-((4-((4-((trimethylsilyl)ethynyl)phenyl)-ethynyl)phenyl)ethynyl)phenyl)ethynyl)phenyl)ethynyl)silane (CAS 176977-40-5), a certified reference material (molecular formula C46H46Si2, MW 655.03 g/mol) for analytical method development and quality control.
Structurally, Triisopropyl((4-((4-((4-((4-((trimethylsilyl)ethynyl)phenyl)-ethynyl)phenyl)ethynyl)phenyl)ethynyl)phenyl)ethynyl)silane (C46H46Si2) contains a polycyclic aromatic system. The molecule exhibits a degree of unsaturation (DBE) of 24.0, corresponding to approximately 24 ring(s) or double-bond equivalent(s). With a molecular weight of 655.03 g/mol, it falls into the high-molecular-weight range. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
